ALVIN RALPH SWAINE, OF DES MOINES, IOWA.

HYDROCARBON-LAMP.

Specification of Letters Patent. Patented J une 11 1912.

Application filed October 1, 1909. Serial No. 520,499.

To all whom it may concern:

Be it known that I, ALVIN RALPH SWAINE, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Hydrocarbon-Lamp, of which the following is a specification.

My improved lamp belongs to that class of gasolene lamps in which gasolene is delivered to the lamp through a pipe, the generating of gas being'accomplished by means of the heat derived from the lamp.

The object of my invention is to provide a lamp of simple, durable and inexpensive construction, especially designed for use in lighting by means of gasolene.

More specifically, it is my object to provide an improved filtering device for the gasolene, so arranged thatit will not become readily clogged, and also so arranged that the filter proper may be quickly and easily detached from the lamp for purposes of cleaning, repair or replacement. A further object is to provide an improved .feed valve device for controlling the flow of gasolene.

A further object is to provide an improved fitting for supporting two inverted gas mantles and for supplying air and gas to the lamp, and also, in this connection, to provide a generating chamber for the gasolene extended through the central portion of said fitting to thereby have the heat from the gas mantles applied to said generating chamber in a direct manner to facilitate the generating of gas.

A further object is to provide a gas light of this kind especially adapted to be easily and readily contained within a suitable globe or lamp shade, and further, in this connection, to provide improved means for supporting a lamp shade and heat deflector from the supporting device.v

A further object is to provide a gas lamp of this kind in which all of the parts may be quickly, readily and easily assembled or detached for purposes of repair or replacement.

My invention consists in. the construction, arrangement, and combination of the various parts of the lamp whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out 1n my clalms, and

illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of a lamp embodying my invention, with part of the shade broken away to show certain details of construction. Fig. 2 shows a central, de

tail, sectional view of a lamp embodying my invention with the shade and mantle deview illustrating the fitting for supporting,

two mantles and the generating tube. Fig. 5- shows an inverted, plan view of same. Fig. 6 shows an enlarged, detail, sectional view illustrating the filtering device used in the filtering tube and the generating tube, and Fig. 7 shows a detail, edge view of the fitting that supports the various parts of the lamp.

Referring to the accompanyingdrawings, I have used the reference numeral 10 to indicate a gasolene supply pipe connected with a tank or other suitable source of supply. This pipe is admitted into a union fitting 11 in which is a gasolene supply pipe 12 communicating with the pipe 10 and made detachable from it by means of said union.

At the lower endof the pipe 12 is a second union fitting 13 connected to a supporting block 14. Thissupporting block 14 is held in position by means'of a bracket 15, de signed to be secured to a support such, for instance, as the ceiling of a building, and screwed into said support is a large pipe 16 surrounding the pipe 12 and having its lower end screwed to a fitting 17, which fitting is open onv its opposite sides as shown in Fig. 7, andwhich is screwed at its lower end to the supporting block 14. In this way, the said supporting block 14: is firmly held in position and the operator may have free access to the union fitting 13, so that the supporting block and the rest of the lamp may be readily, quickly and easily detached from the fitting 17 and the pipe 12. Fixed to the supporting block l l is a series of outwardly extended rods 18, which rods support a metal collar 19, and said collar is adapted to receive and support a lamp shade 20. There is a shoulder on, top of the su porting blockll designed to receive a' efiector 21, as shown in Fig. 3,, the deflector proper being shown in Fig. 1.

The supporting block 14 has a screw threaded opening extended through it horizontally and the passageway 22 leading from said opening to the top of the supporting j these rods is a tube of asbestos or other porous material 27, the ends of which extend beyond the rods 26, and each end is closed by means of a wire 28, the asbestos being of such size as to completely fill and loosely fit into the interior of the pipe 23.. The advantage of havinganumber of rods pass through the asbestos tube is that the rods will hold the tube in position against the interiorof the pipe and form longitudinal passageways around said rods. This is clearly illustrated in Fig. 60f the drawings.- The said filtering device may, at any time, be readily andieasily' withdrawn by first removing the screw plug 24 and then grasping the adjacent end of the filtering device with a small pair of pincers so that in the event the'filtering device'should become clogged or stopped up, it may be removed for cleaning or repairlng purposes.

For regulating thefiow of gasolene to the generating chamber, I have provided a valve stem 29 screwed into the lower end of the valve chamber 25, and having a needle point 30 to enter a reduced passageway 31 leading upwardly from the hollow interior of the valve chamber. 'A fitting 32 is screwed onto the lower end of the valve chamber 25 and is providedwith a central'partition 33 having an opening to receive the valve stem and also having a supporting pipe 34 screwed into its lower end. On the lower end of said pipe 34 is a screw plug 35 having an opening through it for the valve stem 29. A handle 36 is fixed to the lower. end, of the valve stem. Formed on the valve stem 29 above the partition 33 is a collar 37 so arranged that when the valve stem is screwed down it will strike said partition and limit the downward movement of the valve stem. By means of this construction, it is obvious that the valve stem is strengthened and'supported by the tube 34'and that the valve stem cannot be unscrewedfar enough to be wholly withdrawn from the valve casing; and the said fitting'32 also provides-a chamber to receive packing material to prevent a leakage of gasolene downwardly around the valve stem.

The generating and mantle supporting devices are connected with each other and sup- {ported by means of a rod 38 which is screwed the mantle supporting fitting." This fitting is preferably formed complete of a single piece of cast metal and it comprises a hollow body portion 39 having two internally screwthread'ed extensions 40, extending downwardly. In each of these extensions is a slotted plate 41 for spreading and distribut ing the mixed'gas and air and for preventing the ignition of the gas above them. In the central portion of the fitting39 is a solid partition 42'havinga horizontally arranged opening extended through it. This opening is intersected by set-screws 43. The 7 gas mantles 44 are connected with the extensions 40 in the ordinary manner.

My improved generating device comprises a generatlng tube 45 extended through the opening in the partition 42. and having arranged therein a number of rods 46, and an asbestos tube 47 arranged in the samemanner as the filtering device, as before described. The said tube 45 is-firmlyheld in place by the 'set-screw43. 'Atone end of" the tube 45'is ahollow fitting 48 screwed to the tube 45 and having a. hollow plug, 49 screwed into its upper portion to communi cats with the interior thereof, and applied to the plug 49 is a'union 50 to connect the gasolene supply pipe 51 with the plug 49. This gasolene supply pipe 51 communicates with the top of the valve chamber 25. to which it is held by means of a union 52.

The opposite end of the generating tube 45 upper end of the passageway 55. Mounted within the chamber 54 is an. expansion tube for the gas, indicated by the numeral 57. This tube has an opening therein designed to receive the tapered upper end of the small tube 56, and the tubes 56 and 57 are held in proper position by means of a setscrew 58. The outer end of the tube 57 is closed by a screw plug 59 and the other end has a reduced opening 60. Ashort-pipe section 61 is screwed to the block 53 to com municate with the interior of'the chamber 54thereof. This tube is provided with a number of openings 62in its sides and it is connected by means of. a second tube 63 with the part39.

In practical operation, it is obvious that the device may bequickly and easily assembled as all of the parts are fitted to.- gether with screw joints and the entire de vice is very simple and inexpensive in construction. The generating and burning parts are of compact form and" can be stem may be placed at any desired point spaced apart from the side of the globe. The gasolene that enters from the supply pipe 10 flows first through the filtering de vice, which filtering device is of such construction that it will not readily and easily be clogged; and, if by any reason, it should become clogged up, it may be removed and cleaned by simply removing the plug 24. The needle valve for controlling the flow of gasolene is so arranged that the valve stem may be made of any desired length and it is strengthened and braced by means of the tube 34. Furthermore, all danger of.

unscrewing the valve to such an extent as to cause leakage of gasolene is prevented by the partition 33 and the collar 37. By placing the generating chamber in a tube, which tube is contained between and above the two gas mantles, I apply a maximum amount of heat to the generator to quickly convert the gasolene into gas. The means for conducting gas to the fitting that supports the burners is also of simple construction and any of the parts thereof may be readily removed or replaced.
